MG HS Problems: Common Faults, Reliability and Years to Avoid (2019–2026)

The MG HS has become an increasingly popular family SUV thanks to its competitive price, spacious interior, generous equipment and attractive warranty. However, despite offering excellent value for money, the vehicle has experienced several reliability concerns that potential buyers and current owners should understand.

Some of the most frequently reported MG HS problems include automatic gearbox hesitation, infotainment system failures, electrical faults, battery drainage, premature brake wear and occasional suspension noises. Certain plug-in hybrid versions have also been subject to safety recalls.

But does this mean the MG HS is an unreliable SUV? Not necessarily. While some owners have experienced frustrating mechanical and electrical issues, others report trouble-free ownership.

In this comprehensive guide, we'll explore the most common MG HS faults, their symptoms, possible causes, estimated repair costs and reliability differences between model years. We'll also discuss which versions deserve extra attention and whether buying a used MG HS is a sensible decision.

What Are the Most Common MG HS Problems?

The MG HS has several recurring complaints, particularly among owners of first-generation vehicles introduced in 2019.

Some issues involve mechanical components, while others are related to software, electronics or driving characteristics.

The following table summarises the most commonly discussed problems.

Not every problem affects every MG HS. The likelihood of encountering a particular fault depends on the vehicle's age, engine, transmission, mileage and maintenance history.

MG HS Reliability: First Generation vs Second Generation

Before examining individual problems, it's important to understand that the MG HS has undergone significant changes since its introduction.

First-Generation MG HS (2019–2024)

The original MG HS was introduced in 2019 and became available in several international markets.

Depending on the country, buyers could choose a turbocharged petrol engine with manual or automatic transmission. Plug-in hybrid versions were subsequently introduced.

This generation has the longest ownership history, making it easier to identify recurring problems.

Common areas of concern include:

• Automatic gearbox hesitation.
• Infotainment system glitches.
• Battery drainage.
• Electrical accessory failures.
• Brake disc wear.
• Central locking problems.
• Clutch-related noises.

Although the first-generation MG HS offers attractive used-car prices, we recommend inspecting these components carefully before purchasing.

Second-Generation MG HS (2024–2026)

The second-generation MG HS was introduced in 2024 with redesigned styling, updated technology and revised powertrain options.

Depending on the market, versions include petrol, conventional hybrid and plug-in hybrid models.

The newer generation offers improvements in interior technology, efficiency and overall refinement.

However, some reviewers have continued to criticise aspects of the automatic transmission's low-speed behaviour and the touchscreen interface.

Long-term reliability information remains limited because the redesigned model has not been on the road for as many years as its predecessor.

Therefore, problems reported on the original MG HS should not automatically be attributed to the newer generation.

1. MG HS Automatic Gearbox Problems

One of the most widely discussed MG HS issues concerns the automatic transmission.

Some petrol models use a seven-speed dual-clutch transmission, which can behave differently from a conventional torque-converter automatic.

Drivers occasionally report hesitation and jerky movements, particularly in slow-moving traffic.

Symptoms of MG HS Gearbox Problems

Typical complaints include:

• Delayed acceleration when pulling away.
• Jerky movements at low speeds.
• Hesitation when changing between reverse and drive.
• Rough gear changes in heavy traffic.
• Shuddering when accelerating.
• Unusual delays when selecting a gear.

These symptoms can become particularly noticeable during city driving, parking manoeuvres and hill starts.

What Causes MG HS Transmission Problems?

Several factors may contribute to poor transmission behaviour.

Transmission software: The gearbox control system determines when and how gears engage. Software calibration may influence smoothness and responsiveness.

Dual-clutch characteristics: Unlike a conventional automatic, a dual-clutch gearbox engages and disengages clutches electronically. This can produce hesitation under certain driving conditions.

Clutch wear: Excessive wear can cause slipping, vibration or difficulty engaging gears.

Electronic sensors: Faulty sensors or control components may affect transmission operation.

It's important to distinguish between normal transmission characteristics and genuine mechanical defects.

How to Fix MG HS Gearbox Problems

If your MG HS experiences persistent transmission problems, we recommend:

1. Checking for available gearbox software updates.
2. Having the transmission scanned for diagnostic fault codes.
3. Inspecting clutch operation where applicable.
4. Testing the vehicle under different driving conditions.
5. Consulting an authorised MG technician if the problem continues.

Avoid replacing expensive transmission components without a proper diagnosis.

2. MG HS Infotainment System Problems

The infotainment system is another area where some MG HS owners have experienced difficulties.

Although the touchscreen provides useful functions, including navigation, smartphone connectivity and vehicle settings, some versions have been criticised for slow responses and occasional software glitches.

Common MG HS Touchscreen Problems

Reported symptoms include:

• Touchscreen freezing unexpectedly.
• Slow response when navigating menus.
• Display temporarily turning black.
• Bluetooth connectivity problems.
• Apple CarPlay or Android Auto disconnecting.
• Navigation software freezing.
• Delayed response from climate-control menus.

These problems are especially inconvenient when important vehicle controls are integrated into the central display.

How to Fix an MG HS Touchscreen

We recommend starting with a few simple checks.

First, restart the infotainment system using the procedure specified in the owner's manual.

Next, disconnect any connected smartphone and determine whether the touchscreen works correctly without it.

If smartphone connectivity is the problem, try another compatible cable or remove and reconnect the Bluetooth pairing.

A dealership may also be able to install an updated software version.

If the screen continues to freeze or becomes completely unresponsive, a professional inspection may be required.

3. MG HS Battery Problems

Battery drainage is another complaint worth investigating, particularly on older MG HS models.

Some owners have reported experiencing a flat battery after leaving their vehicle parked for several days.

Although batteries naturally deteriorate with age, repeated discharge may indicate an underlying electrical problem.

Symptoms of MG HS Battery Problems

Common warning signs include:

• Engine struggling to start.
• Clicking noises when turning the ignition.
• Central locking not responding.
• Dashboard warning lights appearing unexpectedly.
• Electrical accessories behaving inconsistently.
• Battery repeatedly losing charge.

A weak 12V battery can also generate multiple electronic warning messages.

Why Does the MG HS Battery Keep Going Flat?

Possible explanations include:

• An ageing or defective battery.
• Excessive electrical consumption while parked.
• Faulty charging-system components.
• Frequent short journeys.
• Electrical modules remaining active after the vehicle is switched off.

Determining the exact cause requires proper testing.

How to Prevent MG HS Battery Drainage

We recommend periodically checking battery health and ensuring the vehicle receives adequate charging during normal use.

If the battery repeatedly becomes discharged, a mechanic should test the charging system and check for excessive parasitic electrical consumption.

Replacing the battery without identifying the original cause may not permanently resolve the problem.

4. MG HS Electrical Problems

Modern vehicles rely heavily on electronics, and the MG HS is no exception.

Some owners have reported intermittent electrical problems affecting central locking, sensors and interior accessories.

Common MG HS Electrical Faults

Possible symptoms include:

• Central locking failures.
• Keyless entry not responding.
• Parking sensor errors.
• Reversing camera malfunctions.
• Unexpected dashboard warning lights.
• Intermittent accessory failures.

These symptoms can have several causes, including weak batteries, damaged wiring, faulty sensors or electronic control module problems.

How to Diagnose MG HS Electrical Faults

A professional diagnostic scan should be the first step when multiple electrical systems behave abnormally.

If the problem affects only the remote key, inspect the key fob battery before investigating more expensive components.

For intermittent faults, it can be helpful to record exactly when the issue occurs.

Avoid randomly replacing electrical components because this can increase repair costs without resolving the problem.

5. MG HS Engine Problems

The MG HS has been sold with different petrol and hybrid powertrains depending on the model year and market.

The 1.5-litre turbocharged petrol engine is among the most familiar options.

While the engine has received criticism for its refinement and performance in some applications, this does not mean every MG HS engine suffers from serious mechanical defects.

MG HS Engine Warning Light

An illuminated check engine light can indicate several different problems.

Possible causes include:

• Faulty ignition coils.
• Worn spark plugs.
• Engine management sensor faults.
• Air intake problems.
• Fuel system irregularities.
• Emissions system faults.

We recommend obtaining diagnostic trouble codes before attempting repairs.

MG HS Engine Hesitation

If your MG HS hesitates during acceleration, the cause may involve the engine, transmission or electronic throttle response.

Potential symptoms include:

• Delayed acceleration.
• Uneven power delivery.
• Engine misfires.
• Reduced performance.
• Increased fuel consumption.

A mechanical inspection can help distinguish between normal powertrain calibration and an actual malfunction.

MG HS Overheating Problems

Engine overheating requires immediate attention.

Possible causes include coolant leaks, thermostat faults, cooling fan problems or other cooling-system failures.

If the temperature warning light illuminates or the engine overheats, stop driving as soon as it is safe.

Continuing to operate an overheating engine can cause serious mechanical damage.

6. MG HS Brake Problems

Some first-generation MG HS owners have reported premature brake wear, particularly involving rear brake discs.

Brake components naturally deteriorate over time, but unusually rapid or uneven wear may indicate a problem.

Symptoms of MG HS Brake Problems

Watch for:

• Squeaking or grinding noises.
• Vibrations when braking.
• Uneven brake disc wear.
• Reduced braking performance.
• The vehicle pulling to one side.
• Excessive corrosion on brake components.

What Causes Premature Brake Wear?

Several factors can accelerate deterioration.

These include frequent stop-start driving, sticking brake calipers, corrosion, driving conditions and poor maintenance.

Brake discs may also develop surface corrosion when a vehicle remains parked for extended periods.

How to Fix MG HS Brake Problems

A technician should inspect the brake pads, discs, calipers and related components.

If the rear brakes show unusual wear, the mechanic should also inspect the parking brake mechanism.

Replacing worn components without addressing an underlying caliper problem may lead to repeated premature wear.

7. MG HS Suspension Problems

The MG HS is designed primarily for comfortable everyday driving rather than sporty handling.

However, some reviewers have criticised its relatively soft suspension and noticeable body movement over uneven roads.

This driving characteristic should not be confused with a mechanical suspension failure.

Common MG HS Suspension Symptoms

Signs of a genuine problem may include:

• Knocking noises over speed bumps.
• Clunking when turning.
• Excessive bouncing.
• Uneven tyre wear.
• Poor steering stability.
• Visible damage to suspension components.

Possible causes include worn bushes, damaged shock absorbers, loose suspension components or problems with stabiliser links.

How to Identify Suspension Problems

During a test drive, listen for unusual metallic noises when travelling over uneven surfaces.

A professional inspection should check shock absorbers, suspension bushes, ball joints and other relevant components.

Persistent knocking noises should be investigated before purchasing a used MG HS.

8. MG HS Clutch Problems

Manual MG HS models may experience clutch wear as mileage increases.

Some first-generation vehicles have also been associated with complaints involving clutch release bearing noises.

Symptoms of MG HS Clutch Problems

Potential warning signs include:

• Difficulty selecting gears.
• Clutch slipping under acceleration.
• Rattling when pressing the clutch pedal.
• Vibration when moving off.
• A high clutch biting point.
• Burning smells after repeated clutch engagement.

These symptoms may indicate clutch wear or problems with associated components.

MG HS Clutch Replacement Cost

Clutch replacement costs vary significantly depending on the model, transmission and location.

For a manual MG HS in the UK, a complete clutch replacement may cost several hundred pounds or more than £1,000, depending on labour requirements and the parts involved.

Automatic dual-clutch transmission repairs are different and can be substantially more complicated.

Always request a diagnosis and written quotation before approving repairs.

9. MG HS Plug-in Hybrid Problems

The MG HS plug-in hybrid combines a petrol engine with an electric motor and a rechargeable high-voltage battery.

This system can reduce fuel consumption when the vehicle is charged regularly, but it also introduces additional electrical and mechanical components.

MG HS PHEV Charging Problems

Potential symptoms include:

• Charging not starting.
• Charging unexpectedly stopping.
• Charging-related warning messages.
• Reduced electric driving range.
• Difficulty recognising a charging connection.

Before assuming the vehicle has a fault, check the charging cable, charging station and vehicle settings.

If the problem continues with different compatible chargers, professional diagnosis may be required.

MG HS PHEV Battery Problems

Electric driving range naturally varies depending on temperature, speed, terrain and climate-control usage.

Therefore, a lower-than-expected range does not automatically indicate battery deterioration.

However, a substantial unexplained decrease in battery capacity should be investigated.

When buying a used MG HS PHEV, we recommend requesting information about the battery's condition and the vehicle's charging history where available.

MG HS Hybrid System Warning Lights

A hybrid warning light can indicate several possible electrical or electronic faults.

Because plug-in hybrid vehicles operate with high-voltage components, repairs should only be performed by appropriately qualified technicians.

Never attempt to open or repair high-voltage battery components yourself.

10. MG HS Recall Problems

Some MG HS plug-in hybrid vehicles have been affected by an important electrical safety recall.

In Australia, a recall affecting certain 2021–2022 MG HS PHEV and HS +EV vehicles concerned an electrical ground connection associated with the supplementary cabin heater.

Under specific conditions, incorrectly positioned carpet underlay could interfere with the electrical connection.

If the connection became loose, the associated wiring could overheat and potentially create a fire risk.

A corresponding recall also affected certain MG EHS plug-in hybrid vehicles in the United Kingdom.

How to Check MG HS Recalls

If you own or plan to purchase an MG HS, check whether the vehicle has any outstanding manufacturer recalls.

We recommend contacting an authorised MG dealership and providing the vehicle identification number (VIN).

The dealership can identify applicable recall campaigns and confirm whether corrective work has been completed.

Recall repairs are generally provided without charge when the vehicle qualifies for the manufacturer's campaign.

Importantly, these recalls do not mean that every MG HS or every model year has the same defect.

11. MG HS Problems by Year (2019–2026)

Not all MG HS model years have the same reliability history.

The original generation has a longer ownership record, while the redesigned generation remains relatively new.

The following table provides a practical overview of the areas worth inspecting.

These are inspection priorities rather than confirmed failure rankings.

Which MG HS Years Should You Avoid?

There is insufficient evidence to identify one model year that all buyers should avoid.

However, we recommend exercising extra caution when considering vehicles with:

• Unresolved safety recalls.
• Persistent gearbox hesitation or shuddering.
• Repeated electrical failures.
• Missing service records.
• Unexplained warning lights.
• A history of unsuccessful repairs.

A well-maintained older vehicle can be a better purchase than a newer example with unresolved faults.

12. Is the MG HS Reliable?

The MG HS provides strong value for money, but its reliability record has been mixed.

Owner surveys and automotive reviews of the first generation have identified concerns involving electronics, transmissions, brakes and some interior components.

However, reliability also depends heavily on maintenance, driving conditions and individual vehicle quality.

MG HS Reliability Compared With Competitors

Potential alternatives include:

• Hyundai Tucson.
• Kia Sportage.
• Toyota RAV4.
• Mazda CX-5.
• Honda CR-V.
• Nissan Qashqai.
• Peugeot 3008.

Some competing SUVs have stronger established reputations for long-term reliability.

Nevertheless, the MG HS may offer more equipment for a similar purchase price.

When comparing vehicles, we recommend considering purchase price, fuel economy, maintenance expenses, warranty coverage and expected ownership duration.

Is the New MG HS More Reliable?

The redesigned MG HS offers modernised powertrains and updated electronics.

However, newer technology does not automatically guarantee greater reliability.

Because 2025 and 2026 models have relatively limited long-term ownership histories, it is too early to determine whether they will consistently outperform the first generation.

13. MG HS Repair Costs

Repair costs vary by country, engine, model year, parts availability and labour rates.

The following table provides illustrative UK repair price ranges.

These amounts are approximate budgeting estimates, not fixed prices or verified quotations. Actual costs may be higher, particularly for complex transmission repairs or hybrid electrical components.

Are MG HS Parts Expensive?

Routine maintenance components are generally easier to source than specialised electronic or hybrid components.

However, repair expenses can increase when a vehicle requires:

• An automatic transmission assembly.
• Electronic control modules.
• Specialist sensors.
• Hybrid system components.
• Manufacturer-specific electronic parts.

Parts availability and repair costs may also differ considerably between the UK, Australia and other international markets.

14. MG HS Warranty: Are Common Problems Covered?

One of the MG HS's strongest selling points is its manufacturer warranty.

In markets such as the United Kingdom, MG has offered seven-year warranty coverage, subject to mileage limits and specific conditions.

However, exact warranty terms depend on the vehicle, country and registration date.

What Does the MG HS Warranty Cover?

Eligible manufacturing defects involving mechanical or electrical components may be covered.

Normal wear and tear is typically treated differently.

Components such as brake pads, clutch friction material and tyres may have limited or excluded coverage.

Before buying a used MG HS, we recommend checking the remaining warranty and reviewing the maintenance requirements.

A comprehensive warranty can help reduce unexpected ownership expenses, although it does not eliminate every repair cost.

15. How to Prevent Common MG HS Problems

Although no maintenance routine can prevent every defect, regular inspections and servicing can reduce the likelihood of avoidable mechanical failures.

Follow the Manufacturer's Service Schedule

Use the maintenance intervals specified for your particular MG HS engine, market and model year.

Regular servicing helps identify developing problems before they become more serious.

Check for Software Updates

Transmission behaviour, infotainment performance and certain electronic functions may be influenced by software.

Ask an authorised MG service centre whether any relevant updates are available.

Maintain the Battery

Have the 12V battery inspected periodically.

If the vehicle repeatedly fails to start after being parked, investigate the charging system and potential parasitic battery drain.

Inspect the Brakes Regularly

Brake inspections are particularly important when purchasing a used MG HS.

Look for uneven disc wear, damaged pads, excessive corrosion and abnormal noises.

Investigate Warning Lights Immediately

Unexpected warning messages should not be ignored, particularly those involving the engine, brakes, transmission or hybrid system.

Early diagnosis may prevent a relatively minor issue from developing into a more expensive problem.

16. What to Check Before Buying a Used MG HS

A used MG HS can provide excellent value, but a thorough inspection is essential.

Before purchasing, we recommend completing the following checklist.

Used MG HS Buying Checklist

• Check the full service history.

18. Is the MG HS Worth Buying Despite Its Problems?

The MG HS can still be a worthwhile purchase for drivers who want a spacious, well-equipped SUV without spending as much as they might on some competitors.

Its affordability is particularly appealing in the used-car market.

However, we believe buyers should prioritise vehicle condition over price alone.

A cheap MG HS with recurring electrical faults or transmission problems may become more expensive to own than a better-maintained example.

For first-generation vehicles, we recommend examining the automatic gearbox, infotainment system, battery, brakes and recall history.

For the newer generation, buyers should consider the lack of extensive long-term reliability information.

Ultimately, a well-maintained MG HS with a clean mechanical inspection and remaining warranty protection can represent good value.
